PULP BOTTLE.

Specification of Letters Patent.

Patented J an. 20, 1920.

Application filed July 18, 1918. Serial No. 245,525.

easily and quickly made, which possesses extreme strength, and which is capable of containing liquid or other substances. As a matter of fact the bottle is primarily intended to contain a beverage, for illustration, beer or milk.

.In the drawings accompanying and form-. I

ing part of the present specification I show in detail a form of embodiment of; the invention which to enable those skilled in the art to practise thesame will be set forth fully in the following description. necessarily restrict myself to this particular disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings:

Figure 1 is an elevation of a half'of the bottle in primary condition.

Fig. 2 is a cross Section on the line 22 of Fig. 1, looking in the direction of the arrow.

Fig. 3 is a view corresponding to Fig. 1 of the finished bottle half.

Fig. 4 is a cross section on the line 4-4 of Fig. 8, looking in the direction of the arrow.

Fig. 5 is an elevation of the finished bottle.

Fig. 6 is a top plan view of the same.

Fig. 7 is another elevation of the bottle taken at right angles from Fig. 5.

Fig. 8 is a bottom plan view of the finished bottle.

Like characters refer to like throughout the several views.

The bottle comprises preferably sections, for instance two complemental halves as 2. Fig. 1 shows this half or section at a preliminary point in its production, while Fig. 3 illustrates the same at a later stage in the proceeding. The section 2 (a duplicate of its companion) (nmprises a body portion 3 having a bottom portion 4 ordinarily integral with the body portion, the tapered por- I do not parts tion 5 rising from the body portion. Preferablyextending along the sides and bottom of the section 2 is a fin orbead as 6. Initially (Figs. 1 and 2) this fin or bead is practically a little thicker than the intermediate portion of said section, this intermediate portion being that pa rt of the bottle section which is surrounded by the two lateral and bottom end fins 6. This structure is made in a mold or through the intervention of suitable molding or equivalent means.

After the section 2 is produced, all of it except the marginal fins 6, is by compression or with the aid of suitable molding means, densified or compressed as indicated at 8 in Fig. 4, the marginal fin or body 6 after the primary action being left in its original condition. Obviously the densification of that part of the pulp mass within or surrounded by the two lateral and end fins 6 produces between the fins 6 and the main portion 8,

the channel or rear series of channels 9 as clearly shown in said Fig. 1. This particular view and Fig. 3 which is an elevation of it, is illustrative of a section before it is united with a compleniental section. The inner face of the portion 2 is flat as denoted by 10. The portion :2 is brought into relation with a similar portion, the several flat faces 10 being placed against each other preferably in absolute registration. The

beads 6 are then cohesively united by pressure through the intervention of suitable molding means to produce a bottle like that denoted by 11 in Figs. 5 to 8 inclusive. This bottle it will be seen, has flanges 12 extending along the same from opposite sides v and across the bottom, these flanges 12 being secured by pressing together the two sets of heads 6. The pressure will be such that the cross section of an external bead is practically the same as the thickness of the bottle.

Obtiously these flanges 12 materially strengthen the bottle.

Each section 2 of the body of the bottle has on its bottom beads or tongues 13 at right angles to the bottom ortions of the fins or beads 6 as shown est in Fig. 4. The inner end portions of'these beads or tongues 13 are cohesively united when the face portions of the marginal heads 6 are connected together. The result is that there is produced on the bottom of the bottle as shown best in Fig. 8a cruciform beaded part preferably fiat on its under side and upon which the bottle can rest or be supported and thus maintain the bottle in an upright wardly or as it might otherwise be stated from the outside toward the inside; in fact exactly opposite to that applied in the formation 'of the body. It will be clear that the pressure applied at the top of the section is downward, and this pressure is of such nature as to secure in the external part of the neck, the annular channel in which may be sprung the so-called crown cap. It isnot always necessary to use such a closure, because one of an entirely diiferent nature may be provided to seal, when necessary, the .contents of the bottle.

There may be cases where I prefer to waterproof, for instance by paraflin, the inside and the outside of the bottle. I may also impress upon the bottle while in a mold through the use of a suitable die or dies, an inscription denoting the contents of the bottle and similar indicia. There may be cases, of course, where this may not be necessary, the facts being indicated by printing or by the use of a hand stamp. While the bottom of the bottle is preferably integral with the sections or halvesthereof, this may not be necessary in all cases. v

It will be evident that when external pressures are applied to the halfor section 2 to densify the stock at the ends thereof, the length of this section is appreciably shorttogether their adhering faces are flat, the inner portions of the flat faces being along the inner edges of the sections, while the outer portions are along the beads 6. The beads are actually pressed together and cohere in a thoroughly substantial manner.

What I claim is: v

1. A pulp bottle having two halves, each provided with a marginal bead, the margi nal beads being compressed together.

2. A puln bottle comprising two halv s, each half having a marginal bead, the marginalbeads of the halves being compressed together and being initially of greater cross sectional extent than the intermediate portions of the respective halves.

3. A pulp bottle in sections, each section having a marginal bead along its sides and bottom, the beads being compressed together throughout the complete depth and width of the bottle. I

4. A pulp bottle having two halves, each half having a marginal bead along its sides and bottom, the marginal beads being compressed together the bottom also having beads at right angles to the. other beads and the end portions of which are compressed together.

In testimony whereof I affix my signature in the presence of two witnesses.
